Specification of Letters Patent. Patented Sept. 12, 1916.

Application filed March 11. 1915. Serial No. 13,724

To all whom it may concern Be it known that I, THOMAS PERRY, a citizen of the United States, and a resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Pile-Cutting Machines, of which the following is a full, true, and exact specification.

My invention relates to pile cutting machines and has for its principal object: to provide a machine which may be attached to a pile driver or the like, or used independently to out OK the tops of piles at any desired elevation, grade or shape, of which the principal features are means by which, when attached to a pile driver, my device may be moved forward to cut oil one or more piles and when not in use, may be run back out of the way of the pile driving apparatus, means for raising and lowering the cutting apparatus with respect to the pile, means for swinging the cutting means about a pivot point in order to reach piles somewhat to the side of the machine; means for raising either side or end of the machine in order to cut piles ofi' on a grade or slope.

Other objects will appear as my invention is more fully described in the following specification, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of my device shown attached to a pile driver with parts broken away. Fig. 2 is an enlarged plan view of my device shown separately with parts broken away.

In the drawings, numeral 1 designates pile driver skids which are tied together by struts 2. A tower 3 is mounted upon the forward ends of the skids. An engine 1 is mounted upon the rear of the skids, the engine being provided with the usual haulage drums Secured to the skids 1, are upright guides 6 within which posts 7 are adapted to slide. Posts 7 are pivotally secured to cross pieces 8. Channel rails 9 are secured to cross pieces 8 and are upturned at either end to prevent wheels 10 from running out of the rails. Wheels 10 are mounted in pairs upon axles 11 which are secured to the under side of a circular table 12. A ball race 13 is out in the top of table 12 and is adapted to contain balls 1 1.

A turn table member to which is secured an extension or swinging arm is mounted upon the circular table 12 by a king bolt 15. The turn table and swing arm are com- .posedof a lower member 16 and an upper member 17 with a filler 18 between. The swinging arm portion is made up of the filler 1'8and extensions 19 and 20 from members 16 and 17 respectively. A sheave 21 is mounted on a shaft 22 in suitable bearings on the outer end of the swinging arm. A circular saw 23 is secured to the lower end of shaft 22 and is suspended below the swinging arm as shown.

An engine 24 or any other suitable source of power is mounted upon the turn table top and is provided with a sheave wheel 25. An endless belt or rope 26 passes around sheave 25, idlers 26 and 26 which are secured to the turn table top, and around sheave 21 which is thus driven by the engine 2a.

A segmental rack 27. is secured to the rear periphery of table 12 and is adapted to engage a pinion 28 which is secured to a shaft 29. The shaft 29 passes through bearings in turn table members 16 and 17, and is provided with a handle 30 at its upper end. The purpose of rack 27 and pinion 28 is to provide a means of rotating the turn table and swinging arm with respect to the circular table 12.

A straight rack 31 is secured to one of the rails 9 and is adapted to engage a pinion 31 which is secured to a shaft 32. Shaft 32 passes through a bearing 33 which is secured to one of the axles 11 and is provided with an operating handle 34 at its upper end. The purpose of rack 31 and pinion 31 is to form a means of moving the turn table and swinging arm portions forward or backward with respect to the rails 9.

The turn tables, circular tables, swinging arms, axles and wheels may be said toconstitute a movable carriage upon which the saw and motive power are mounted.

Bearings 35 are secured to the upper portion of guides 6 and support shafts 36 upon which are mounted spools 37 and sprockets 38, the latter of which are connected by an endless chain 39. Cables 41-0, one end of each of which is secured to one of the posts 7, are wound upon spools 37. Turnbuckles ll are inserted in the cables 40 near the posts 7 and together with the said cables, form means for suspending and adjusting the level grade and slope of the rails and carriage with respect to the pile driver. A drive pulley 42 is mounted upon the rear shaft 36 and is adapted to be driven by a belt 43 from one of the drums 5 of the engine 4. The driving of pulley 42 rotates shafts 36 and thus causes the spools 37 to revolve and wind up the cable 40 which raises the rails and carriage. Ratchets 43- and pawls i i are used to hold the shafts 36 in any desired position. A gradual releasing of the belt 43 will allow the rails and carriage to descend to a position somewhat below the skids 2 as is frequently necessary in cutting off a pile 45. The raising and lowering operation of the carriage may be accomplished by hand power if so desired instead of the belt 43.

It is evident that my device is adapted for use upon a water driver, land driver, a skidded frame upon the ground, or upon a track on the ground. It is also evident that it may be used to clear land, cut off stumps or trees and the like, as well as piles. In cutting off a pile or the like at any desired elevation, the carriage is run out until the saw is adjacent to the pile, the track and carriage are raised or lowered to the proper elevation, and if the pile is to be cut on a slope or grade, the turnbuckles are adjusted to put the saw in such slope and grade, at which time the engine 24 is started and the carriage advanced until the saw has cut ofi the pile.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein, will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and I therefore, desire to avoid being limited to the exact form shown and described, except as defined in the appended claims.

Having described my invention, what I claim as new and desire to protect by Letters Patent, is

1. In a pile cutting machine including a rigid supporting frame work and a vertically movable and tilting saw supporting frame, the combination of a plurality of parallel and vertically channeled guides secured together in a rigid frame, similar winding drums mounted upon shafts which are supported from the tops of said guides and which are connected so as to rotate in unison, posts pivoted to said movable frame and slidable within said channeled guides, cables secured to the tops of said posts and wound upon said drums, whereby said movable frame may be raised and lowered, and turnbuckles interposed in said cables adja- Copies of this patent may be obtained for five cents each, by addressing the cent said posts, whereby said movable frame may be tilted with respect to the stationary frame.

2. In a machine for cutting piles and the like, including a supporting framework con sisting of a stationary and a movable part, the combination of means upon the stationary part of said supporting framework for raising vertically, lowering and tilting bodily the movable part of the said supporting framework with respect to the stationary part, a wheeled carriage mounted upon the movable part of the framework and radiall y swingable cutting means mounted upon the said carriage.
